Query for the collective brain: Advanced 7-year-old reader, nothing too scary or fantastical.

Request via the FB:

My nephew is 7, but is a pretty advanced reader. My sister-in-law is having difficulty finding books that give him the reading challenge he wants, without content that is too far beyond his years. (He doesn't like things that are too mysterious/scary and isn't quite ready for fantasy themes like wizards/witches, etc.) He's already powered through just about everything by E.B. White, some Beverly Clearly, old Thornton Burgess, etc. - basically my sister-in-law and I have been raiding our own childhood bookshelves for ideas. Do you or any of your followers have any suggestions for a budding bookworm? Would love some more modern options, but he's also just as happy in the classics.

This request is geared a bit younger than my specialty—off the top of my head, Roald Dahl's less-scary titles (like, NOT The Witches), Geronimo Stilton, the Judy Moody and Stink books, the My Weird School series, Eric Berlin's Winston Breen books, and Blue Balliett come to mind, though those are all pretty broadly ranged in terms of reading level—so I'm passing it along to you all.

Any suggestions?
